The implantable device includes a docking member extending from the proximal end of the housing of the implantable device including a covering surrounding at least a portion of the docking member configured to facilitate retrieval of the implantable leadless cardiac pacing device.

An insertion device that allows gaining access to the left ventricle of the heart, via the tissue forming the wall of the right ventricle and via the ventricular septum, which includes a tubular shaft with a lumen extending there through, the shaft comprising distal, proximal and central sections, whereby the distal and proximal sections are disc-shaped extended thus forming each a double disc and whereby the central section links the distally placed double disc with the proximally placed double disc and whereby pressure valves are fixed inside the shaft preferably on its distal and proximal end.

Disclosed is a delivery system for a component, for example, a splitting lead. A splitting lead can have a proximal portion to engage a controller and a distal portion to split apart into sub-portions that travel in multiple directions during implantation into a patient. The delivery system can include a handle and a component advancer to advance and removably engage a portion of the component. The component advancer can be coupled to the handle and advance the component into the patient by applying a force to the portion in response to actuation of the handle by the operator. Also, the delivery system can include an insertion tip with first and second ramps to facilitate advancement of first and second sub-portions into the patient in first and second directions. The leads may have various electrode configurations including, for example, wrapped or embedded electrodes, helical or elliptical coils, thin metallic plates, etc.

An electrode for use with an implantable medical device includes an alloy and a conductive oxide layer on a surface of the alloy. The alloy includes iridium and at least one of cobalt and iron. The conductive oxide layer includes iridium oxide. The conductive oxide layer has a thickness greater than about 5 nanometers.

A system and method for managing atrial-ventricular (AV) delay adjustments are provided and includes electrodes configured to be located proximate to an atrial (A) site and at least one of a left bundle branch (LBB) site or a HIS site. An IMD has a header that includes a right atrial (RA) header port, a right ventricular (RV) header port and a left ventricular (LV) header port. The system includes memory configured to store program instructions and one or more processors that, when configured to execute the program instructions measure an AV interval corresponding to an interval between an atrial paced (Ap) event or an atrial sensed (As) event and a sensed ventricular (Vs) event. The system sets a candidate AV delay based on the AV interval and a bundle branch adjustment (BBA) value, measures a QRS characteristic of interest (COI) while utilizing the candidate AV delay in connection with delivering a pacing therapy by the IMD and adjusts the BBA value and reset the candidate AV delay based on the BBA value as adjusted. The system repeats the adjust, reset and measure to obtain a collection of QRS COIs and corresponding candidate AV delays, selects one of the candidate AV delays, that corresponds to a select one of the QRS COIs, as a BBA AV delay and manages the pacing therapy, utilized by the IMD, based on the BBA AV delay.

The present invention is related to an implantable medical device for treating breathing disorders and cardiac disorders by delivering stimulation energy to the phrenic nerve, hypoglossal nerves and cardiac muscle tissues.

A device for extending a lead according to some embodiments includes a body, a tubular member coupled to the body, the tubular member comprising an outer surface, wherein the outer surface is sized to insert into an inner lumen of a lead, the tubular member is movable between a first configuration in which the tubular member slides into the lead, and a second configuration in which at least a portion of the tubular member expands to engage an inner surface of the lead; and, an actuation mechanism operatively coupled to the tubular member, the actuation mechanism configured to move the tubular member between the first configuration and second configuration.

Methods, devices and program products are provided for under control of one or more processors within an implantable medical device (IMD). Sensing near field (NF) and far field (FF) signals are between first and second combinations of electrodes coupled to the IMD. The method applies an arrhythmia detection algorithm to the NF signals for identifying events within the NF signal and designates events marker based thereon and monitors the event markers to detect a candidate arrhythmia condition in the NF signals. The candidate under-detected condition comprises at least one of an under-detected arrhythmia or over-sensing. In response to detection of the candidate arrhythmia condition, the method analyzes the FF signals for a presence of an under-detected arrhythmia indicator. The method delivers an arrhythmia therapy based on the presence of the under-detected arrhythmia indicator in the FF signals and the candidate under-detected arrhythmia condition in the NF signals.

A wireless cardiac stimulation device is disclosed comprising a controller-transmitter, a receiver, and a stimulating electrode, wherein the stimulating electrode and the receiver are separately implantable at cardiac tissue locations of the heart and are connected by a local lead. Having separately implantable receiver and stimulating electrodes improves the efficiency of ultrasound mediated wireless stimulation by allowing the receiver to be placed optimally for reception efficiency, thereby resulting in longer battery life, and by allowing the stimulating electrode to be placed optimally for stimulus delivery. Another advantage is a reduced risk of embolization, since the receiver and stimulating electrode ensemble is attached at two locations of the heart wall, with the connecting local leads serving as a safety tether should either the receiver or the stimulating electrode become dislodged.

A system for treating cardiac arrhythmias comprising a generator including: a sensing circuitry configured to evaluate one or more identified signals representative of electrical activity of the heart and detect an arrhythmia, a control circuitry that is configured to control delivery of a therapy in response to the detected arrhythmia, the therapy including a first stage of electrical pulses delivered via at least a first electrode, wherein the first set of electrical pulses is configured to destabilize and/or terminate a reentry associated with the arrhythmia, and a first lead coupled to the generator, wherein the first lead includes the first electrode.
